4-chloro-2-methylphenol

4-chloro-2-methylphenol is an organochlorine compound with the molecular formula C7H7ClO and CAS number 1570-64-5. This chlorinated phenolic compound has a molecular weight of 142.58 g/mol and belongs to the family of substituted phenols. It is characterized by a phenol ring substituted with both a chlorine atom at the 4-position and a methyl group at the 2-position, making it a versatile chemical intermediate in various industrial applications.

4-chloro-2-methylphenol typically appears as a white to light yellow crystalline solid at room temperature. It has a characteristic phenolic odor and exhibits moderate solubility in water while being readily soluble in organic solvents such as ethanol, acetone, and benzene. The compound has a melting point around 45-50°C and demonstrates typical phenolic chemical behavior, including reactivity towards oxidizing agents and the ability to form salts with bases.

4-chloro-2-methylphenol serves primarily as a chemical intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. It is used in the production of antimicrobial agents, preservatives, and disinfectants due to its phenolic structure. The compound also finds application in the manufacture of dyes, pigments, and polymer additives. Additionally, it serves as a building block for more complex organic molecules in fine chemical synthesis and research applications.

4-chloro-2-methylphenol requires careful handling due to its Acute Toxicity 3 and Skin Corrosion 1A classifications. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work should be conducted in well-ventilated areas or under fume extraction systems. Avoid inhalation of dust or vapors, and never eat, drink, or smoke while handling the substance. Emergency eyewash stations and safety showers should be readily accessible.

4-chloro-2-methylphenol should be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed to prevent moisture absorption and contamination. Store away from incompatible materials such as strong oxidizing agents, strong bases, and reactive metals. The storage area should be equipped with appropriate containment measures and be accessible only to trained personnel. Maintain storage temperatures below 25°C for optimal stability.

Immediate action is critical due to the substance's corrosive properties. For skin contact, immediately remove contaminated clothing and flush the affected area with copious amounts of water for at least 15 minutes. For eye contact, rinse immediately with water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and monitor breathing. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult emergency services for severe exposures.

4-chloro-2-methylphenol disposal must comply with local and national hazardous waste regulations. The substance cannot be disposed of in regular waste streams due to its toxic and corrosive properties. Arrange disposal through licensed hazardous waste contractors who can handle chlorinated organic compounds. Incineration at high temperatures in approved facilities is typically the preferred method. Empty containers should also be treated as hazardous waste. Always consult local environmental authorities for specific disposal requirements.

4-chloro-2-methylphenol is classified under ADR as Class 6.1 (toxic substances), Packing Group II, indicating moderate toxicity requiring specific transport precautions. It must be packaged in UN-approved containers with appropriate labeling including toxic substance pictograms. Transport vehicles must carry proper documentation and emergency response information. Drivers require ADR training for dangerous goods transport. The substance should be secured to prevent spillage and kept away from foodstuffs during transport.

4-chloro-2-methylphenol falls under various regulatory frameworks including REACH registration requirements for European markets and CLP classification showing GHS06, GHS05, and GHS09 pictograms. While not currently listed as an SVHC (Substance of Very High Concern), it requires safety data sheet provision and proper hazard communication. Users must comply with occupational exposure limits where established and follow workplace safety regulations. Import/export may require additional permits depending on destination countries and quantities involved.
